Oral SurgeryScrub technique refers to the method of scrubbing the operator's hands and forearms before donning gown and gloves. This is essential for maintaining a sterile environment and reducing the risk of surgical site infections.

Oral PathologyPagets disease characteristically exhibits hypercementosis of the entire dentition due to the abnormal bone remodeling process affecting the alveolar bone and periodontal ligament space. The disease can also cause root resorption in severe cases. Albert-Schonberg disease (osteopetrosis), lathyrism, and low-grade periapical inflammation do not typically cause generalized hypercementosis of the entire dentition.

ProsthodonticsWhen replacing all missing mandibular incisors with PFM restorations, both canines should be used as abutments. The canines provide adequate support for the four-unit bridge due to their long roots and favorable crown-to-root ratio. Including premolars would create an unnecessarily long span and increase the risk of failure. The canine-to-canine bridge is biomechanically sound and commonly successful.

RadiologyPA view is not suitable for viewing middle third facial fractures due to superimposition of structures. Occipitomental views (10° and 30°) and lateral skull views provide better visualization of middle third fractures by avoiding superimposition of the skull base and cervical spine.

Prosthodontics
Explanation: Anterior incisal contacts during posterior
masticatory functions are not desirable because they can lead to instability and
improper function of the complete denture. Ideally, posterior teeth should
provide the primary occlusal contacts during chewing, while anterior teeth
should not interfere with these functions. This helps maintain a balanced
occlusion and prevents excessive wear or damage to the denture.

NEETMDSViruses, when isolated in crystalline form, are found to be nucleoproteins. This means they are composed of a nucleic acid core (either DNA or RNA) surrounded by a protein coat (capsid).

Oral SurgeryHypoglycaemia may occur in a patient taking insulin and undergoing extraction when the procedure is done on an empty stomach. This is because insulin lowers blood sugar levels, and without food to balance the insulin's effect, the patient could experience a dangerous drop in blood glucose. It is important to ensure that the patient eats before the surgery and that glucose levels are monitored.

Physiology
Answer: 2) A-beta fibers have the second highest conduction velocity after A-alpha fibers and are responsible for touch, kinesthetic sense, and pressure sensation, not motor supply to skeletal muscles. A-alpha fibers have the highest conduction velocity and are indeed responsible for motor supply to skeletal muscles.
